Looks like the bead not fully seated all the way around.
Let enough air out that you can push the sidewall and bead in, and work your way all the way around the wheel on both sides to ensure the tube is not trapped between the tire and rim. If you do see tube peeking out at you, let a bit more pressure out and work the tube into the tire.
Then inflate the tire to the max recommended pressure, spin the wheel to make sure the bead is not slipping out, and if it is still wiggling, then give it another 10 or 15 percent over the max pressure and the tire should pop into place. Be sure to let that extra pressure out before riding 'cause it's rattle your teeth out.
